Patients and methods: 30 patients were treatment planned for extraction of mandibular first molar teeth, leaving 30 sockets for the study. Sockets were divided randomly into two equal groups. Sockets were grafted as follows: Group (I) sockets were grafted by Osteon II Collagen mixed with Hy A, Group (II) sockets were grafted by sticky bone graft. A cone beam computed tomography (CBCT) radiographs at one day, 3 and 6 months were postoperatively done to assess bone density and tooth socket dimensions. Microscopic evaluation was performed at 6 months before implant insertion. All readings were recorded and analyzed statistically. Results: There is a high statistically significant difference between study groups as regards the mean values of bone density, bone height, and percentage of volume change. In another the side, other parameters showed insignificant differences between the study groups. Histological study referred to more maturation of bone in group I than group II. Conclusion: The results clearly concluded that both Osteon II Collagen mixed with HyA and sticky bone are successful in achieving clinical and 3D volumetric socket bone preservation with superiority for Osteon II Collagen mixed with HyA .}, keywords = {Keywords: socket preservation,Osteon II Collagen,Sticky bone,Hyaluronic Acid (Hy A),cone beam computed tomography (CBCT)}, url = {https://edj.journals.ekb.eg/article_102927.html}, eprint = {https://edj.journals.ekb.eg/article_102927_27aaefc8b2bd8d076fa12293fd897c2f.pdf} } @article { author = {Abdullah, Abdel Aziz and Abdelmabood, Abdelbadia}, title = {Autogenous bone ring transplant versus sticky bone in defective socket augmentation with simultaneous implant placemen}, journal = {Egyptian Dental Journal}, volume = {66}, number = {Issue 3 - ِJuly (Oral Surgery)}, pages = {1495-1507}, year = {2020}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2020.30239.1128}, abstract = {Aim : This study was designed to evaluate efficacy of autologous concentrated growth factors enriched bone graft matrix (sticky bone) bone versus autogenous chin bone ring in the premolar–molar region with simultaneous implant placement . Patients and methods: Twenty patients had fresh defective extraction sockets in the mandibular premolar-molar region with severely compromised buccal bone divided randomly into equal groups (in group I; sockets were augmented by sticky bone, and in group II; sockets were augmented by chin bone ring). Then dental implants were placed in the same visit and were covered by collagen membrane in both groups. Clinical and radiographic examinations were done to evaluate the soft tissue, stability of dental implant, crestal bone level, and bone density around dental implants immediate (1st week) postoperatively and at, 3rd, 6th, 9th, and 12th month postoperatively. All readings were recorded and evaluated statistically. Results: Clinically, group II showed little postoperative complications in comparing group I. in the other side, both groups did not show any statistical significance difference in implant stability and probing pocket depth parameters. Radiographically, group I had highly statistical significance more than group II (P <0.001) in bone density and marginal bone level parameters along time of study. Conclusion: Both techniques were successful methods for 3D augmentation of severely defective sockets with immediate placement of dental implant with superiority for autogenous bone ring in aspects of marginal bone level, and density of bone around dental implant.}, keywords = {bone ring,Sticky bone,defective socket,Immediate implant,Fibrin glue}, url = {https://edj.journals.ekb.eg/article_102929.html}, eprint = {https://edj.journals.ekb.eg/article_102929_c595cab3ca855bddeb0fa217de2863d2.pdf} } @article { author = {Elkhouly, Haytham and Elbokle, Nader and Khashaba, Mohammed}, title = {Evaluation of Primary Stability in Immediate Non Submerged Root Analogue Zirconium Implants: A Preliminary Study}, journal = {Egyptian Dental Journal}, volume = {66}, number = {Issue 3 - ِJuly (Oral Surgery)}, pages = {1509-1518}, year = {2020}, publisher = {The Egyptian Dental Association (EDA)}, issn = {0070-9484}, eissn = {2090-2360}, doi = {10.21608/edj.2020.32794.1142}, abstract = {Objective: The aim of the present study was to evaluate the primary stability of immediate, custom made zirconium root analogue implant. Our 2ry outcome was to evaluate Marginal bone changes at the day of implantation, & after 3 months. Patients and methods: This study included 8 immediate implant placements in fresh sockets in esthetic zones using custom made zirconium implants. A Pre-operative CBCT was obtained for each patient to get the measurements & dimensions of the un-restorable teeth. Patients were prepped for the procedure under LA. Extraction of teeth was done atraumatically. The extracted remaining roots were disinfected then mounted on the laser scanner to produce an stl.file of the remaining roots. Then using the CAD software to modify the root analogue by adding macro retentive “blebs” on the lateral surfaces of custom made zirconium implant. Transferring the design to the milling machine using zirconium blocks. The implants were subjected to surface treatment using sand blasting method, & then sterilized. Patients were recalled after 3 days for insertion; and implantation using tapping technique, to achieve primary stability. The primary stability was measured using periotestM device as a primary outcome. Standardized paralleling technique was used to assure the seating of the implant inside the socket after insertion, & for evaluation of the marginal bone changes as a 2ry outcome. Results: All custom made zirconium implants failed to osseointegrate Conclusion:Within the limitations of this study, the authors could not measure the stability nor the marginal bone changes of custom made zirconium implants}, keywords = {custom-made zirconium dental implants,Primary implant stability,osseointegration,Root Analogue}, url = {https://edj.journals.ekb.eg/article_102931.html}, eprint = {https://edj.journals.ekb.eg/article_102931_19860bb98c42b86dee383d02d6c6f7d1.pdf} }
